When you say "Vee threads", do you mean a standard 60⁰ thread? What TPI? Notice the photo above is about 20 TPI, but isn't Vee, nor is it a true square thread like the 12 TPI of most Rolling Blocks. Perhaps more like a ACME thread? I didn't measure the degree since I didn't need to cut any threads of it. Just had it apart for cleaning and took photo.
